[Mac] When adding an Object or Type with Long Test, New/Select Buttons get pushed off edge.

[CartBlanche]

Steps:

1. Scroll to Object or Type Selector
2. Click associated button (New/Select)
3. From Popup select Object with a long name

Current Result....

Expected Result..
If Text it too long, is should Centre ellipsis, so that full text is visible when moused over. New/Select button should always be visible.Essentially similar behaviour to what was added for the property text.
